Horizon Steel Frontiers is an MMORPG in the Horizon universe, made by NC with Guerrilla and revealed at G-Star in November 2025. It is set in the Deadlands, a new southern region of deserts and overgrown skyscrapers modelled on Arizona and New Mexico; you play your own hunter, not Aloy.

Hunters come from a tribe: Nora, Tenakth, Utaru or Oseram. Combat leans towards Monster Hunter: charged-blade melee, breaking machine parts and group hunts of big targets. You can ride machines and flying mounts; group dungeons are Cauldrons. It runs on Unreal Engine 5 with touch-first controls, on PC via NC's PURPLE launcher.

No public tests yet. In June 2026 NC named the first half of 2027 for launch, with the first beta promised after a Gamescom 2026 demo. No business model yet; it is mobile-first, with no PS5 version planned.
